The main hit was taken by small businesses & entertainment industry. Plus there's a huge rise of unemployment in regions after the exodus of big international companies that had their production factories in Russia. Inflation grows quite quickly. The quality of products (from food to literally everything else) has dropped significantly. The whole economy is more or less isolated from the outside which allows Russia to retain a very favorable ruble price but they're not doing it by improving its value, they're doing it by restricting its trade.
The biggest issue is mid-to-long term effects on a more complicated production cycles. Every complicated machinery needs a steady supply of new details to keep up functioning and this supply is limited to say the least. The aviation have taken the hit earlier due to how closed off the market for those details are (and how important it is to prevent anything from happening — in other production you can risk it a bit more) — they are tearing down some planes to get details for other planes and this is not a sustainable strategy.
Plus Russia still gets an enormous amount of money from the export of energy sources which it uses to cover the ever-growing cracks in its economy but that input of cash is going to dry up pretty soon.
Here's a decent read that is still more or less readable if you translate it from Russian via google:
